It has become the European standard, probably not so useful for TNs as most or all ER-negatives are assigned in the high risk category. The test looks at a gene expression profile and categorizes tumors into high, intermediate, or low risk of recurrence. There's also a calculation of anticipated benefit from chemo for the high risk people. It's a great test in that it saves a lot of women from going through chemo unnecessarily. The woman who developed the test and saw it through the approval process in Europe is coming to UCSF in a permanent position. She is just wonderful, professionally and as a human being. Just stellar. Expect more from her!

I talked about the Mammaprint test at the hospital where the test was developped. They told me that TN Mammaprint test outcome tested 96% as aggressive. Since the test wasn't in the insurance plan last year I decided to skip the test and save EUR 2.675,--. The Mammaprint is a very promissing test but it's not the european standard. As far as I know in the Netherlands (where the test was developed) it's still not covered by the insurance policies and therefor not part of the standard care.

My surgeon did the mammoprint at the time of the biopsy. I was a bit concerned that the results came back as high probability of reoccurance. I discussed this with the onc and he advised that all TN would have high prob. of reoccurance according to the Mammoprint.

Jan, that's right. Mammaprint is extremely conservative, and biases against most any ER- cancer. I don't know if any TNs come out as low risk - actually, I'll check that out, and if I find out I'll let you know.

Concerning mamma print,mine came back low risk, so I will not have chemo. I was Dax March 1and had bilateral mastectomy,stage 1,grade2,ki67 was4%. I had estrogen sensitive bc in 2003. Had lumpectomy,radiation and took arimadex.

Hi Annie, please can you tell me how old you are? I have decided not to have chemo, but although most of the time I am happy with my choice, if I get low, the fear creeps in. Just nearing the end of 20 rads, and I'm 50. Had 2 lumpectomies, in same place, and clean lymph. Thanks.

Hi Mary - what did your second opinion say? I have said no to chemo. My tumour was 6mm, apparently 3mm went up the biopsy needles and 3mm they got out at surgery! Mostly happy with decision but when I feel low the fear creeps in. Thanks. x

Hi. I am 71..I have been avoiding meat except for salmon and other fish and also not eating any dairy products for three years.. I moved to a small town in me Oregon last year from Tempe Arizona..This town has a lot of seventh day adventists who are very healthy eaters and a lot of them work in the local hospital. It is a scarey decision to have or not have chemo. I hope it is the right decision for me..I will try to do the right diet and exercise and hope it will be all ok..good luck
